Auxiliary lenses for eyeglasses

ABSTRACT

An eyeglass device includes a primary and an auxiliary spectacle frames for supporting lenses. The primary spectacle frame includes two legs pivotally coupled to two side extensions and includes two magnetic members secured in the rear and side portions. The auxiliary spectacle frame includes two legs engaged on the primary spectacle frame and each having a magnetic member for engaging with the magnetic members of the primary spectacle frame so as to secure the spectacle frames together and so as to prevent the auxiliary spectacle frame from moving downward relative to the primary spectacle frame.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to auxiliary lenses, and more particularlyto auxiliary lenses for eyeglasses.

2. Description of the Prior Art

A typical spectacle frame having an attachable one-piece slide-on rim isdisclosed in U.S. Pat. No. 4,070,103 to Meeker. In Meeker, a spectacleframe includes a magnetic material secured to the peripheral portionthereof for facilitating attachment of the auxiliary lens rim cover tothe spectacle frame. The lens rim cover also includes a magnetic stripfor engaging with the magnetic material of the spectacle frame.

Another typical eyeglasses are disclosed in U.S. Pat. No. 5,416,537 toSadler and comprise first magnetic members secured to the temporalportions of the frames and second magnetic members secured to thecorresponding temporal portions of the auxiliary lenses.

In both of the eyeglasses, the auxiliary lenses are simply attached tothe frames by magnetic materials and have no supporting members forpreventing the auxiliary lenses from moving downward relative to theframes such that the auxiliary lenses may easily move downward relativeto the frames and may be easily disengaged from the frames when theusers conduct jogging or jumping exercises. In addition, the magneticmaterials are embedded in the frames of the primary lenses and of theauxiliary lenses such that the frames should be excavated with four ormore cavities for engaging with the magnetic members and such that thestrength of the frames is greatly decreased.

The present invention has arisen to mitigate and/or obviate theafore-described disadvantages of the conventional spectacle frames.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide auxiliarylenses which may be stably secured and supported on the frames.

In accordance with one aspect of the invention, there is provided aneyeglass device comprising a primary spectacle frame for supportingprimary lenses therein, the primary spectacle frame including two sideportions each having an extension extended therefrom for pivotallycoupling a leg means thereto, the primary spectacle frame including tworear and side portions each having a projection secured thereto, theprimary spectacle frame including an upper portion, a pair of firstmagnetic members secured in the projections respectively, an auxiliaryspectacle frame for supporting auxiliary lenses therein, the auxiliaryspectacle frame including two side portions each having an arm extendedtherefrom for extending over and for engaging with the upper portion ofthe primary spectacle frame, and a pair of second magnetic memberssecured to the arms respectively for engaging with the first magneticmembers of the primary spectacle frame so as to secure the auxiliaryspectacle frame to the primary spectacle frame. The arms are engagedwith and supported on the upper portion of the primary spectacle frameso as to allow the auxiliary spectacle frame to be stably supported onthe primary spectacle frame and so as to prevent the auxiliary spectacleframe from moving downward relative to and so as to prevent theauxiliary spectacle frame from being disengaged from the primaryspectacle frame.

The projections and the first magnetic members are arranged lower thanthe upper portion of the primary spectacle frame, the second magneticmembers are extended downward toward the projections for hooking on theprimary spectacle frame so as to further secure the auxiliary spectacleframe to the primary spectacle frame. The auxiliary spectacle frame maybe prevented from disengaging from the primary spectacle frame.

Further objectives and advantages of the present invention will becomeapparent from a careful reading of a detailed description providedhereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1 to 4, an eyeglassdevice in accordance with the present invention comprises a primaryspectacle frame 10 for supporting primary lenses therein. The primaryspectacle frame 10 includes two side portions each having an extension11 extended rearward therefrom for pivotally coupling leg 12 thereto.The primary spectacle frame 10 includes two projections 13 secured tothe rear and side portions thereof for supporting magnetic members 14therein. An auxiliary spectacle frame 20 is provided for supporting theauxiliary lenses therein and includes two side portions each having anarm 21 extended rearward therefrom for extending over and for engagingwith the upper portion of the primary spectacle frame 10 (FIGS. 5 and6). The auxiliary spectacle frame 20 also includes two magnetic members22 secured to the arms 21 therefor for engaging with the magneticmembers 14 of the primary spectacle frame 10 such that the auxiliaryspectacle frame 20 may be stably supported on the primary spectacleframe 10, best shown in FIGS. 5 and 6.

It is to be noted that the arms 21 are engaged with and are supported onthe upper portion of the primary spectacle frame 10 such that theauxiliary spectacle frame 20 may be stably supported and secured to theprimary spectacle frame 10. The auxiliary spectacle frame 20 will notmove downward relative to the primary spectacle frame and will not beeasily disengaged from the primary spectacle frame when the usersconduct jogging or jumping exercises.

It is further to be noted that the projections 13 and the magneticmembers 14 are secured to the primary spectacle frame 10 and themagnetic members 22 are secured in the arms 21. The magnetic members 14,22 are not embedded in the frames 10, 20 such that the frames 10, 20 arenot required to be formed with cavities therein and such that thestrength of the frames 10, 20 will not be decreased.

As shown in FIGS. 3-7, the engaging surfaces between magnetic members 14in primary spectacle frame 10 and the magnetic members 22 in theauxiliary spectacle frame 20 lie in a plane that is substantiallyhorizontal when the eyeglass device is worn.

Referring next to FIG. 7, it is preferable that the projections 13 andthe magnetic members 14 are located slightly lower than the upperportion of the primary spectacle frame 10; and the end portions of thearms 21 and/or the magnetic members 22 are slightly extended downwardtoward the projections 13 such that the arms 21 and the magnetic members22 may hook on the primary spectacle frame 10 and such that theauxiliary spectacle frame 20 may further be stably supported and securedto the primary spectacle frame 10.

In one embodiment, as shown in FIG. 7, magnetic members 14 and 22 arenot in contact with each other; magnetic members 14 and 22 are engagedwith, but not supported on, each other. Instead, the arm 21 securing themagnetic member 22 is supported on an upper side portion of the primaryspectacle frame 10. As shown in FIG. 7, the upper side portion can be anupper part of the side portion securing the projection 13.

Accordingly, the eyeglass device in accordance with the presentinvention includes an auxiliary spectacle frame that may be stablysecured to the primary spectacle frame and will not move downwardrelative to the primary spectacle frame and will not be easilydisengaged from the primary spectacle frame when the users conductjogging or jumping exercises. In addition, the magnetic members are notembedded in the frames such that the strength of the frames will not bedecreased.

Although this invention has been described with a certain degree ofparticularity, it is to be understood that the present disclosure hasbeen made by way of example only and that numerous changes in thedetailed construction and the combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as hereinafter claimed.
